Aperture vision

J. J. Gibson이 The ecological approach to visual perception에서 제안한 시지각의 범주 중 하나.

If the exposure period is made longer, the eye will scan the pattern to which it is exposed, fixating the parts in succession unless the subject is prohibited from doing so. I call this aperture vision, for it is a little like looking at the environment through a knothole in a fence.
